Help, the System Always Rewards Me with Strange Knowledge

I found that my boyfriend Ji Yan has been acting strangely recently. He began to analyze the top, middle and bottom notes of perfumes in detail, used his knowledge of "postpartum care of sows" to make accurate cuts in the debate, and even tried to use game theory to teach me "how to eat cake gracefully". Just when I almost thought that his orientation had changed, he held an introductory book "Luban's Ten Siege Weapons" and said to me with a sad face: "Xiaoxiao, believe me... It's all really forced by the system!" I looked at the boyfriend in front of me who exuded the light of "knowledge is power" and fell into deep thought: Does this system... Have any misunderstanding about "green tea"?
